Descriptions of some of the animals which occurred, are given in the notes below.[189] The prairie wolves[190] roam over the plains in considerable numbers, and during the night, the principal season of their hunts, they venture very near to the encampment of the traveller. They are by far the most numerous of our wolves, and often unite in packs for the purpose of chasing deer, which they very frequently succeed in running down, and killing. This, however, is an achievement attended with much difficulty to them, and in which the exertion of their utmost swiftness and cunning are so often unavailing, that they are sometimes reduced to the necessity of eating wild plums, and other fruits, to them almost indigestible, in order to distend the stomach, and appease, in a degree, the cravings of hunger. Their bark is much more distinctly like that of the domestic dog, than of any other animal; in fact the first two or three notes could not be distinguished from the bark of a small terrier, but these notes are succeeded by a lengthened scream. The wonderful intelligence of this animal is well worthy of note, and a few anecdotes respecting it may not be amiss. Mr. Peale constructed and tried various kinds of traps to take them, one of which was of the description called "a live trap," a shallow box reversed, and supported at one end, by the {154} well known kind of trap sticks, usually called the "figure four," which elevated the front of the trap upwards of three feet above its slab flooring; the trap was about six feet long, and nearly the same in breadth, and was plentifully baited with offal. Notwithstanding this arrangement, a wolf actually burrowed under the flooring, and pulled down the bait through the crevices of the floor; tracks of different sizes were observed about the trap. This procedure would seem to be the result of a faculty beyond mere instinct. This trap proving useless, another was constructed in a different part of the country, formed like a large cage, but with a small entrance on the top, through which the animals might enter, but not return; this was equally unsuccessful; the wolves attempted in vain to get at the bait, as they would not enter by the route prepared for them.
